Using the law of sins:

Sin(angle) = Opposite Leg / Hypotenuse

Sin(30) = AB /10

Solve for AB:

AB = 10 * sin(30)

AB = 10 * 1/2

AB = 5

The answer is A.

The table below shows the different times it takes Paula to drive to work each day depending on the rate at which she drives.
Cerrena [4.2K]
From the values in the table, we can multiply the speed by the time to find out the amount of miles she travels a day. This is shown below:

30 mph * 2.5 hours = 75 miles
40 mph * 1.875 hours = 75 miles
50 mph * 1.5 hours = 75 miles
60 mph * 1.25 hours = 75 miles 

Therefore, she travels 75 miles to work. Given a speed of 24 mph, we divide 75 miles by 24 to find out how long it takes her to travel that far:

75 miles / 24 mph = 3.125 hours

A cyclist is riding a bicycle whose wheels have a diameter of feet. Suppose the wheels turn at a rate of revolutions per minute.
SCORPION-xisa [38]

Answer:

a.2010 rad/min

b.2412 feet/min

Step-by-step explanation:

We are given that

Diameter of wheel,d=2.4 feet

Radius,r=\frac{d}{2}=\frac{2.4}{2}=1.2feet

a.Rate=320 rev/minute

1 rev=2\pi radian

320 rev/minute=320\times 2\pi=640\pi radian/minute

Where \pi=3.14

Angular speed=640\times 3.14=2010 rad/min

b.Speed,v=r\omega

v=2010\times 1.2=2412 feet/min
